Daniel Joseph Luland has been charged with two counts of intimidation after approaching, recording and following Mr Elliott, who was then police and emergency services minister, in August 2020.
Giving evidence in the Local Court on Friday, Mr Elliott called Mr Luland's conduct "quite aggressive" and "quite physically intimidating" as the pair walked down Old Northern Road towards the Grove Street Shopping Centre in Baulkham Hills.
"When people pass that threshold, I think a reasonable person would probably be quite cautious when this sort of behaviour is conducted. And let me tell you it is very unusual for that kind of behaviour to occur in the Hills District," Mr Elliott said.
The now transport minister said he was on heightened alert after having a "gut full" of death threats and stalking experienced during his seven years as a politician.
In recorded footage of the August 2021 conversation, which was posted on social media and played to the court, Mr Luland describes how the "tyrannical" NSW government had illegally taken away its citizens' rights through its COVID-19 lockdowns.
Mr Luland is also heard talking about a "media blackout", amendments to federal legislation which permitted the use of United Nations forces on Australian soil and the "racist" lockdown of southwest Sydney during the Delta outbreak.
The footage shows Mr Luland tell another man, Stephen Parnell, to "f*** off" after he came to the aid of the then police minister.
Mr Elliott and Mr Parnell both claim they were intimidated by Mr Luland's conduct.
From the witness box, Mr Parnell described Mr Luland's behaviour as harassment.
"I thought that this guy's up to no good. This could be actually a bit nasty," he told magistrate Eve Wynhausen.
The prosecution claims Mr Luland's tone, behaviour and persistence in following Mr Elliott amounted to intimidation and that both he and Mr Parnell felt fearful for their safety.
Luland's defence lawyer Vinny Vijay told the court that his client's behaviour may have been annoying, but it did not rise to the level of intimidation and that the footage did not show any intent to intimidate.
Mr Vijay said the conversation had begun "quite cordially", noting that his client had maintained his distance and had not attempted to physically block the NSW politician from walking to the shopping centre.
Ms Wynhausen will deliver her decision on Friday afternoon.
